That's basically Coulter's message here. Because Palin has been so damaged by the MSM, she shouldn't run.
Which would just further encourage the MSM to do the same to other conservative politicians.
Coulter’s point to me was that Palin’s supporters are so annoying that they cause her to have a lower opinion of Palin herself.
And I agree with her to the extent that some of Palin’s fans are annoying.
